To' all fwwm' it may concern:

Be it known that l', HERBERT 1t. KEITHLEY, a citizen of the UnitedStates, and resident of Michigan City, county of La Porte, and State or indiana, have invented certain new and useful Improvements in Draft-Arms for Railway-Cars, of which the following' is a speciiication, and which are illustrated lin the accompanying drawings, forming a part thereof,

The invention relates to draft arms adapted to reinforce and strengthen the sills ot a car and `to carry the draft and bung lugs with which the coupler mechanism coperates. More specically, it relates to draft arms formed of pressed steel and having a over and extending beyond the car bolster.

The objects ci the invention are to secure, in a device of this character, increased strength and adaptability to draft gears varying in length,

The invention consists of a structure such as is-hereinafter described, and as illustrated in the accompanying drawings, in which- Figure 1 is a detail longitudinal section of the underraining of a car, the draft arrn being shown in elevation;

Fig. 2 is' a plan view of the draft armdetached; an

Fig. 3 is a sectional view on the line 8-3 The end sill of4 a -car is represented at 10,

and one of its center sills at 11. The draft arm comprises a plate havinga portion 12 adapted to lie alongside of the inner face of the sill 11, its forward end abutting against the end sill 1G and its rearward end'projecting over and to a considerable distance beyond the car bolster 13. prises a portion 14' extendin :Trein the portion 12 and in t therewith. The forward end tion 1d extends under the sill downwardly e same plane of the. por- 10 and its rearwardend abuts against the bolster 13.

An angle bar 15, riveted to the arm section 1li, bears against the under face of the sill 11, and vis secured thereto by means of bolts A11 instanding iange 17. is formed along arm section 12, and

the upper margin oi the y an outstanding flange 18 is formed along the outer margin of -thesection 1d. The section providedlwith an outstanding 12 is also s delige 19, extending .trein the forward face The arm also comof vthe bolster 13 to the rearward end of the arm and underlying the sill lland bolted theretog'as shown at 20.

A lug 2l, preferably of pressed steel, is riveted to the outer face of the arm section 14 and abuts af. 1,ainstA the bolster 13, this lugl fitting snugly between the flange 18 and the angle bar 15, to both of which it is preferably riveted. A draft lug 22 and a bung lug 23ers riveted to the inner face of the arn1.secti0n 14n, the upper row of rivets associated with each of these lugs as securing means for the angle bar 15. The buiiing lug 23 may,^as shown, overlap the lug 21, in which case securing rivets', as 24, 25,`may be common to both. Should it be desired to space the draft and buing lugs a greater or less distance than as indicated in the drawings, the buiing lug may be set entirely forward of the lug 21, in which case there would be no rivets common to both; or itV may be set farther back, in which case more than a single set of rivets would be common to the two lugs.

in service bullng stresses are transmitted 'to the arm through thellug 23, and from provides an extended bearing surface, and

this lug is of substantial strength because of its upper and lower webs or flanges 26, 27. A tie-plate 28 is preferably 'riveted to the flange 19 back of the bolster 13, and abutting thereagainst, and will extend across to the companion arm, to which it will also be secured.
